Yaitskyi S. Low-emission float-glasses with strengthening magnetrone coatings

Object of research: float glasses with low-emission coatings and technologies for their production. Subject of research: technological and physico-chemical regularities of the I-glass with a soft coating with the necessary strength and optical characteristics obtaining. The purpose of the dissertation is the development of the composition and technological parameters of the energy-saving I-glass with reinforced magnetron coatings production for use in construction and architecture. Standard and special materials science methods according to current regulations and international standards are used. Theoretical results: for the first time the linear character of the temperature dependence of the erosion depth of the glass furnace bacor lining by the melt of alkali-calcium silicate float glass in the range of 1400 - 1560 оС was established; the principles of soft magnetron coatings strengthening for obtaining low-emission Double Low-E glasses and adjusting their spectral and mechanical characteristics have been developed. Practical results: compositions and technological parameters of multifunctional low-emission float glasses with reinforced magnetron coatings obtaining to be tempered. Novelty of work: establishment of arrangement regularities of nanolayers of film system Si3N4 / NiCr / Si3N4 for endurance of the float glasses heat treatment. The implementation of the work results at Lysychansky Glass Plant LLS allowed to increase by 94% the production of auitable products - float glass with soft coatings, which is almost not inferior to the best foreign counterparts, but is less expensive and is widely used in glazing high-rise buildings.
